ALBERT J. WVEISS, OF NEWV YORK, N. Y.

HEATiNG-STOVE.

SPECIFICATION forming part of Letters Patent No. 308,222, dated November 18, 1884.

Application filed June 9, 1883. (N model.)

To aZZ whom it may concern:

Be it known that I, ALBERT J. Wmss, a

. subject of the King of Prussia, residing at New York, in the county and State of New York, United States of America, have invented certain new and useful Improvements in Heating-Stoves, of which the'following is a specification sufficiently full, clear, and exact to enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part thereof.

The object of the invention is to secure economy of fuel; and to thisend it consists of a stove of peculiar construction, as hereinafter described and claimed, whereby a thorough or approximately complete combustion of the fuel is attained.

In the accompanying drawings, Figure 1 is a front elevation of this improved stove. Fig. 2 is avertical central section on line x m, Fig.

'1. Fig. 3 is a vertical central section on line 3 y, Fig. 2. Fig. 4 is a transverse section on line 2 2, Fig. 2. Fig. 5is a transverse section on line to 10, Fig. 2. Fig. 6 is a transverse. section on line 1) c, Fig. 2. Fig. 7 is a transverse section on line a a, Fig. 2. Fig. 8 is a transverse section on linet t, Fig. 2. Fig. 9 is a transverse section on line 8 s, Fig. 2.

Similar letters of reference indicate corresponding parts in the different figures.

The fire-pot of this stove is provided with a closed top, 9, a side opening, 8, for the supply of fuel through the door 8, a grate, d, at its bottom, and a grated opening, 6, on the rear side near its top. Below the fire-pot is an ashpot, q, provided with a door, 1). An outer case or shell, 0, of larger diameter than the fire-pot b, surrounds thelatter, forming an annular flue-space, a, between said fire-pot and casing. Arranged a short distance above the fire-pot is a horizontal plate, h, which forms with the top plate of the fire-pot a horizontal flue, h. The top plate of the fire-pot extends to the outer casing of. the stove and closes the annular flue-space a, excepting the segmental opening at the front of the stove, which forms a communication between said flue-space a and the horizontal flue h. A horizontal segmental plate, is, above the plate h, forms with said plate a short horizontal flue, h said plate h having an opening at the rear of the stove, through which communication is effected between the backward horizontal flue h and the return horizontal flue 7L2. A vertical plate, it, extends from the front edge of the horizontal plate 7c upward to near the top of the stove, forming with the upper casing or dome, m, a vertical flue at the front of the stove, which communicates with the horizontal flue 7L2. A vertical plate, 0, extends downward from the top of the stove to near the horizontal plate k, and forms with the plate a a central downward flue, Z, and with the rear portion of the casing or dome m an upward flue, Z". The flue Z communicates at the top of the stove with thefiue'Z and above the plate It with the flue Z with which latter the escape-pipe is connected near the top of the stove. The doors 8 and p are preferably so constructed as to be rendered air-tight after the gases have been consumed.

The operation is as follows: The fire-pot being filled with anthracite coal or other suitable fuel and the fire started, the top plate and sides will become highly heated or red-hot. The gases of combustion will escape from the fire-pot through the opening 6 into the annular space a, and thence pass around the fire-pot in contact with the heated sides thereof to the front of the stove, thence upward through the segmental opening into the horizontal flue it, over the heated top of the fire-pot to the rear of the stove, thence upward into thehorizontal flue h and forward again to the vertical flue Z, thence upward through said flue to the top of the stove, thence downward through the central flue, Z, thence upward through the flue Z to the smokepipe. The gases thus impinge against the redhot side and top of the fire-pot, having long continuous contact therewith, whereby the gases are thoroughly consumed.

The arrangement of flues in the upper portion or dome of the stove forms a very extended radiating-surface.

I am aware that a stove the fire-pot of which has a closed top and a side opening communicating with a vertical flue is not new; but in that case the products of the gases are conducted immediately away from the fire-pot, and the advantages secured by the arrangement of horizontal flues, as in my invention, are not obtained.
